Efi return pressure?
Currently installing a pro-flo efi and remote sump. I'm using the abandoned factory vent line for my return. I'm also thinking I can T into that line with the remote sump vent line. Does anyone know what the pressure is on a typical efi return line? I'm hoping it doesn't back feed return fuel into the sump. If so, I guess I'll add a check valve.
Thanks |

Re: Efi return pressure?
you will want the same size as feed or next size down .
if the vent is the tiny 1/4" line then not a good idea . it will restrict and hold pressure . you want the return to be as free flow as possible.
